Smartphones and other mobile devices have come a long way from being simple tools for just calls and texts — they’ve become essential for storing both personal and sensitive business information. Today, our phones and tablets carry everything from photos and banking details to critical business data, making them prime targets for cyberthreats.
In sectors like healthcare, protecting mobile data isn’t just about security; it's a legal requirement. HIPAA mandates that patient information remains private, making mobile security crucial for compliance, and in order to do this, you must develop a clear mobile security blueprint.
What is mobile security, and why is it important?
Mobile security refers to the protection of both the hardware (devices) and software (applications and data) of mobile devices against unauthorized access and cyberthreats. This type of security is essential, as mobile devices are now gateways to both personal and professional information. A compromised device can give hackers access to sensitive details, including bank account information, confidential business emails, and even private client data.
The stakes are even higher for healthcare providers, as they work in an industry where data security is directly tied to regulatory compliance. As sensitive patient data is a regular target of cybercriminals, HIPAA (the Health Insurance Portability and Accountability Act of 1996) mandates strict measures to ensure that information remains secure. A real-world example of what can happen without proper mobile security is the 2018 case involving a major US healthcare provider, UnityPoint Health. The organization suffered a data breach exposing the personal information, including medical details and Social Security numbers, of over 1.4 million patients.
Such a breach could easily happen due to inadequate mobile security measures, such as using easily guessable passwords (e.g., “password”, “123456”), neglecting software updates, or connecting to unsecured Wi-Fi networks. Worse, many threat actors these days deploy sophisticated phishing attacks that convince even the most savvy mobile device users that they are interacting with a legitimate online entity
Developing a mobile security blueprint
Creating a mobile security blueprint involves a series of proactive steps to protect devices, data, and users from threats. Consider these essential mobile security measures:
Assess your mobile security needs
Conduct a comprehensive inventory of all mobile hardware, such as smartphones, tablets, and any other portable devices that access company data. You must also make and maintain a list of all software and applications installed on these devices, including business-critical apps and third-party tools.
Knowing exactly what devices and apps are in use lets you identify potential security gaps, establish which devices need protection, and set tailored security policies. Having an inventory of mobile device applications will also allow you to monitor for potential risks, such as outdated software, unauthorized devices accessing company data, or apps that may not comply with your organization’s security standards.
Prevent the misuse of administrative privileges
Administrative privileges are elevated permissions granted to users or applications, allowing them to make significant changes to devices, install software, and access sensitive data. While necessary for certain users and functions, these privileges are a potential security risk if misused.
If administrative access falls into the wrong hands — either through phishing, malware, or weak security policies — cybercriminals can gain control over mobile devices, leading to unauthorized access, data theft, or system manipulation.
Limit administrative privileges to only those that absolutely need them and monitor their usage closely. Implement regular audits to track any unusual activities associated with these privileges, such as unauthorized app installations or access to sensitive data.
Authenticate and enforce strict access controls
Enforce the use of strong, unique passwords , and require them to be updated regularly. Weak passwords are one of the easiest ways for unauthorized users to gain access to sensitive information.
Bear in mind that passwords can be easily cracked, making them insufficient as a standalone security tool. Pairing passwords with multifactor authentication (MFA), however, significantly enhances protection. MFA creates an additional layer of security by requiring not just a password but also a second form of verification, which can be a fingerprint or a one-time code sent to a trusted device. This makes it much harder for unauthorized users to gain access, even if they have the password.
Implement device and data protection measures
Always encrypt your data, whether it's at rest in a device or in transit through networks. Encryption scrambles data, making it unreadable without a decryption key, adding a crucial layer of security.
And given the possibility of mobile devices being lost or stolen, ensure your organization has the lstools to remotely track and wipe devices. This reduces the risk of data exposure and ensures confidential information doesn’t fall into the wrong hands. Crucial to this initiative is leveraging mobile device management (MDM). MDM software can help monitor, manage, and secure mobile devices across your organization. Consider a comprehensive MDM solution that offers robust features such as centralized security policies, device tracking, remote wiping, and data protection.
The convenience that mobile devices offer comes with significant security risks. Implementing these tips will help you build a strong mobile security plan to protect your critical data.
